[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. PCBs require dicing during the manufacturing process.

[0003] Currently, a common challenge in PCB board cutting is that typically only one V-groove can be cut into a PCB board in a single processing step. This means that when production demands the division of a large or complex circuit board into multiple smaller pieces, the cutting operation must be repeated multiple times, requiring precise positioning and cutting each time. This undoubtedly increases the complexity and time cost of the processing flow. Utility Model Content

[0012] Furthermore, the adjustment assembly includes at least two connecting frames that are rotatably connected to the outer sides of at least two of the sleeves, and a vertical rod is vertically installed on the upper end face of the connecting frame;

[0017] Furthermore, the two clamping components are symmetrically distributed from left to right, and the shape of the two clamping plates is a cuboid that is hollow inside and missing on one side and the front and back sides.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1This embodiment provides a PCB board segmentation device for performing multi-segment segmentation on a PCB board, thereby improving the segmentation efficiency of the PCB board.

[0028] It includes a base plate 1, two slide rails 2, two sliders 3, a connecting plate 4, an X-axis motion module 5, two clamping components 6, and a cutting component 7; the two slide rails 2 are both set on the base plate 1 along the X direction and are arranged symmetrically from left to right; the two sliders 3 are slidably connected to the outside of the two slide rails 2 respectively; the connecting plate 4 is set between the opposite sides of the two sliders 3 and is in contact with the upper surface of the base plate 1.

[0029] The X-axis motion module 5 is set on the lower surface of the base plate 1. A moving block 501 is connected to the X-axis motion module 5. Corresponding to the moving block 501, a sliding groove is opened in the interior of the base plate 1 along the X-axis direction. The moving block 501 is slidably connected in the sliding groove and is connected to the connecting plate 4. Two clamping components 6 are respectively set on two sliders 3 for fixing the PCB. The cutting component 7 is installed on the base plate 1.

[0030] In actual use, the PCB board is placed between two clamping components 6 and fixed by the clamping components 6. Then, the operation of the X-axis motion module 5 pushes the moving block 501, the connecting plate 4 and the two sliders 3 to move along the extension direction of the slide rail 2, so that the PCB board moves to the bottom of the cutting component 7 and the cutting component 7 performs multi-segment cutting processing on the PCB board.

[0031] Please see Figure 2-3 In order to divide the PCB board into multiple segments, the slitting assembly 7 in this embodiment includes a support frame 701 mounted on the upper surface of the base plate 1. A rotating shaft 702 is rotatably connected between the left and right sides of the inner wall of the support frame 701 via bearings. A motor 703 with its output end connected to the rotating shaft 702 is provided on the support frame 701. At least two sleeves 704 are provided on the outer side of the rotating shaft 702. Cutting wheels 705 are provided on the outer side of the sleeves 704 and in the middle section of the outer surface of the rotating shaft 702. The support frame 701 is also provided with an adjustment assembly for adjusting the distance between two adjacent cutting wheels 705.

[0032] In actual use, the rotation of the output end of the motor 703 drives the rotating shaft 702 connected to it to rotate, and the rotating shaft 702 drives the cutting wheel 705 on its outer side to rotate. That is, when the PCB board is moving, the cutting wheel 705 rotates to cut the PCB board.

[0033] In addition, the spacing between two adjacent cutting wheels 705 can be adjusted by adjusting the components, thereby cutting PCBs of different sizes.

[0034] Furthermore, in order to ensure that the sleeve 704 can still transmit power with the rotating shaft 702 while moving left and right, a limiting rib 706 is provided on the outer side of the rotating shaft 702 along its axial direction, and at least two sleeves 704 are slidably connected to the outer side of the rotating shaft 702 and the limiting rib 706.

[0035] In actual setup, the shape of the inner wall of the sleeve 704 is adapted to the shape of the outer surface of the rotating shaft 702 and the limiting rib 706. That is, when adjusting the distance between two adjacent sleeves 704 and two adjacent cutting wheels 705, the sleeves 704 on the left and right sides can be driven to slide on the outside of the rotating shaft 702 by adjusting the component. At the same time, when the rotating shaft 702 and the limiting rib 706 rotate, they can drive the sleeves 704 and the cutting wheels 705 to rotate.

[0036] In detail, in order to facilitate the adjustment of the distance between two adjacent cutting wheels 705, the adjustment component in this embodiment includes at least two connecting frames 707 that are rotatably connected to the outside of at least two sleeves 704 respectively, and a vertical rod 708 is vertically installed on the upper end face of the connecting frame 707.

[0037] A movable groove is formed on the inner top wall of the support frame 701 along the Y-axis. A vertical rod 708 is slidably connected inside the movable groove. A cylinder 709 is provided on the rear side of the support frame 701. An adjusting plate 710 is drivenly connected to the output end of the cylinder 709. The adjusting plate 710 is slidably connected to the upper end face of the support frame 701. At least two adjusting grooves 711 are formed inside the adjusting plate 710. At least two vertical rods 708 are respectively inserted into the two adjusting grooves 711.

[0038] In actual use, when the output end of the cylinder 709 extends, it can push the adjusting plate 710 forward. Through the cooperation of the vertical rod 708 and the adjusting groove 711, when the adjusting plate 710 moves forward, the vertical rods 708 on the left and right sides will move in opposite directions. The vertical rods 708 drive the connecting frame 707 and the cutting wheel 705 connected to them to move in opposite directions, thereby increasing the distance between two adjacent cutting wheels 705.

[0039] Conversely, when the output end of the cylinder 709 retracts, it can drive the adjusting plate 710 to move backward, and at the same time drive the left and right vertical rods 708, the connecting frame 707, and the cutting wheel 705 to move in opposite directions, so that the distance between two adjacent cutting wheels 705 decreases accordingly.

[0040] It should be noted that the adjustment slots 711 on the left and right sides are arranged in a figure-eight shape, and the connecting frame 707 is in the shape of an inverted U.

[0041] Preferably, there are five cutting wheels 705, and the left and right cutting wheels 705 are symmetrically arranged on both sides of the middle cutting wheel 705.

[0042] Please see Figure 4 In order to fix the PCB board, one of the clamping components 6 in this embodiment includes a clamping plate 601 installed on the upper end face of the slider 3. A fastener 602 is threaded to the inner top wall of the clamping plate 601. The bottom end of the fastener 602 is rotatably connected to a lower pressure plate 603 through a bearing. The lower pressure plate 603 is slidably connected to the inner wall of the clamping plate 601. The two clamping components 6 are symmetrically distributed from left to right. The shape of the two clamping plates 601 is a cuboid that is hollow inside and missing one side and the front and back sides.

[0043] In actual use, the PCB board is placed on the inner bottom wall of the two clamping plates 601 and below the lower pressure plate 603. The lower pressure plate 603 is pushed downward by rotating the fastener 602, so that the lower pressure plate 603 is in contact with the upper surface of the PCB board, thereby fixing the PCB board.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
